  34 <H1>Additions</H1>
  35
  36 <P>CUPS 1.2 includes many new features from the 1.0.x releases.
  37
  38 <H2>Filters</H2>
  39
  40 <H3><CODE>imagetoraster</CODE>, <CODE>imagetops</CODE></H3>
  41
  42 <P>The image file filters have been upgraded to support conversion of
  43 Microsoft Bitmap ("BMP") and Alias PIX files.
  44
  45 <H3>pdftops</H3>
  46
  47 <P>A new pdftops filter has been developed that is based on the
  48 excellent Xpdf 0.90 software from Derek B. Noonburg. The new filter is
  49 faster, smaller, and considerably more reliable than the
  50 Ghostscript-based filter in CUPS 1.0.
  51
  52 <H3>pstoraster</H3>
  53
  54 <P>The <CODE>pstoraster</CODE> filter has been integrated with GNU
  55 GhostScript 5.50. The new RIP supports most Level 3 PostScript language
  56 features.
  57
  58 <H3>rastertoepson</H3>
  59
  60 <P>The new <CODE>rastertoepson</CODE> filter supports EPSON printers
  61 using the ESC/P or ESC/P2 command sets. PPDs are supplied for 9-pin,
  62 24-pin, Stylus Color, and Stylus Photo printers.
  63
  64 <H2>User-Defined Printers and Options</H2>
  65
  66 <P>The new <CODE>lpoptions</CODE> command allows users to configure default
  67 document options and create additional "instances" of existing printers,
  68 each with unique options.
  69
  70 <P>The <CODE>lp</CODE>, <CODE>lpr</CODE>, and <CODE>lpstat</CODE> commands
  71 have been upgraded to use this option and printer instance information
  72 automatically.
  73
  74 <H2>Daemons</H2>
  75
  76 <P>CUPS 1.2 includes two new daemons that provide enhanced network printing
  77 support.
  78
  79 <H3>cups-lpd</H3>
  80
  81 <P>The <CODE>cups-lpd</CODE> daemon provides support for clients using the
  82 Line Printer Daemon protocol.
  83
  84 <H3>cups-polld</H3>
  85
  86 <P>The <CODE>cups-polld</CODE> daemon provides remote polling services for
  87 the scheduler.
  88
  89 <H2>Commands</H2>
  90
  91 <P>CUPS 1.2 includes several new printing commands.
  92
  93 <H3>lpoptions</H3>
  94
  95 <P>The <CODE>lpoptions</CODE> command provides user-defined printers and
  96 options.
  97
  98 <H3>lpmove</H3>
  99
 100 <P>The <CODE>lpmove</CODE> command moves a print job to a new destination.
 101
 102 <H3>lpinfo</H3>
 103
 104 <P>The <CODE>lpinfo</CODE> command lists the available PPD files or devices.
 105
 106 <H2>IPP Implementation</H2>
 107
 108 <P>CUPS 1.2 adds support for the <CODE>set-job-attributes</CODE>
 109 extension operation as well as two new CUPS-specific extension
 110 operations to determine which devices and printer drivers are available
 111 on the system.
 112
 113 <P>Further information on the CUPS implementation of IPP can be found
 114 in CUPS-IPP-1.2.
 115
 116
 117 <H1>Changes</H1>
 118
 119 <P>CUPS 1.2 includes many changes from the 1.1.x releases.
 120
 121 <H2>Directory Structure</H2>
 122
 123 <P>The directory structure in CUPS 1.2 has been modified to conform to the
 124 Filesystem Hierarchy Standard, 2.2. The following table describes the
 125 new file locations.

 185
 186 <H2>IPP Implementation</H2>
 187
 188 <P>CUPS 1.2 is based on version 1.1 of the Internet Printing Protocol.
 189
 190 <P>The new scheduler supports the <CODE>create-job</CODE> and
 191 <CODE>send-document</CODE> operations. In addition, the
 192 <CODE>job-sheets</CODE>, <CODE>job-sheets-default</CODE>, and
 193 <CODE>job-sheets-supported</CODE> attributes are now supported for
 194 banner pages.
 195
 196 <P>The <CODE>CUPS-get-printers</CODE> and <CODE>CUPS-get-classes</CODE>
 197 operations have been upgraded to support limited filtering based upon
 198 the <CODE>printer-type</CODE>, <CODE>printer-location</CODE>,
 199 <CODE>printer-info</CODE>, and <CODE>printer-make-and-model</CODE>
 200 attributes.
 201
 202 <P>The <CODE>CUPS-add-printer</CODE> operation now supports the
 203 <CODE>ppd-name</CODE> attribute to specify a locally-available PPD file
 204 rather than sending the PPD file from the client with the request.
 205
 206 <P>Further information on the CUPS implementation of IPP can be found
 207 in CUPS-IPP-1.2.
